Tiling onto Plywood

[Droopy]

that was more of a precaution than an accusation drew mate...:lol:

Have we met? :lol:

Drew i think you would know :lol:

Ready in 1 hr ???? dear me

Yes, ready in 1 hour.
This is an occupation...livelyhood...................not a hobby..............:yawn:

Truly, remarkable..where does the water..mixed with the powder...escape?

Just as with cement based addy, it doesn't dry as such, it is a chemical reaction that makes it set.
Just that with gypsum addy, the reaction is that bit quicker.

Anwer the Question Drew...Where does the water, we put into the powder go ?

I did.
Just like it does with cement based addy, it acts as the catalyst for a chemical reaction. it does NOT "dry out", it cures. And this stuff cures fast.
I suppose you also think that Concrete sets when all the water somehow dries up?

Why don't you just admit you were wrong, instead of scrapping the bottom of the barrel for reasons to still say you are right?

A decent proportion of water, we must agree does soak into the substances it makes contact with....it dosn't magically disappear, it defies laws of chemistry,if fast setting adhesives or plasters are used the water content needs to evaporate/dissipate, before totally cured.....so to grout them before proper set time, is to trap unwanted moisture......Gaz

are talking about tiling on plaster or "paper" and tiling with rapid adhesives or both :whatchutalkingabout Drew it may be a usfull product ideal for plasterboard but your not tiling to plaster with plasterboard which is my point

Suppose the easiest way to answer this question is to put some of the stuff on a plaster wall and scrape it off straight way. If it leaves a stain on te wall as I suspect it would than water will disipate into the substrate to a certain extent, chemical reaction or not!

This comes along the lines of a previous thread about removing tiles from plasterboard walls. If the tiles and adhesive were only stuck to the paper lining, why does it take the plaster with it when you take the tiles off? Seems to me the slower adhesive sets - either by reaction or dispersion - the more likely that plasterboard will come away with the tile. This is an observation based admittedly on my very short experience of tiling. I would be interested in other peoples opinions and experiences.
